Indirect water heater

I have a proposal to install a 40 gal indirect water heater along with a new boiler install. I currently have a 50 gal electric heater. It is 10 y/o and provides all the hot water that we need.

Cost to install the new HE indirect heater is $2K. I'm thinking that even if my electric HWH dies I can replace it myself and the difference in energy costs doesn't justify the install cost of a new indirect HWH.

Am I missing something?

Personally..... I'd stay with a standard water heater. Less cost, fewer problems with mineral buildup.
Tankless require a large electric service sometimes nearing 100A just for it.

Pete - this is a tanked 40 gal water heater using the boiler as a heat source.

That would be an indirect storage tank not indirect water heater and it would be dependent on boiler fuel.

Sorry Pete. Not my field of expertise. Just using the terminology from the proposal and the internet. This is what they are proposing in a 40 gal size.

How big a boiler are they putting in? Or are you using the existing?And how big? What type of fuel?

If gas yes they go indirect hands down..

That burnham wants 150kk btu input to reach its ratings of 300gph..And 106k btu for 200gph

Id be Leary as for that very reason we install the HTP indirects.

The SSC35 which is a 40 gallon tank has super fast recovery and only needs input of 53k [email protected] Thats a winner there. And needs a pump at 8 gpm..

The math says if you have a 100k btu boiler you will indeed get the 300gph rating with the HTP.

Just my thoughts..

Mike, I talked it over with myself and we decided to stick with our electric HWH until it dies. Way less efficient than the boiler heated, but it does the job for just the two of us.
